PROBLEM TO BE SOLVED: To reduce occurrence of such a situation that a key cannot be opened, in an intercom system capable of remote unlocking by using a portable terminal in place of the intercom master unit.SOLUTION: Multiple communication terminals (interphones 10 and portable communication terminals 30) used by multiple registered persons as alternative call destinations are registered previously, and the interphone 10 performs camera processing in response to depression of a call button, acquires the movie image and face feature points of a visitor, and then transmits notification data NF including the face feature points to an authentication server 20. The authentication server 20 performs face authentication based on the face feature points included in the notification data NF, transmits call notification CR including the authentication results to multiple communication terminals at the alternative call destinations, and transmits the movie image information of the visitor to a communication terminal that has transmitted a response request Req for this call notification. The interphone 10 unlock the entrance door upon receiving unlock permission data ULkp even from one of the communication terminals of the alternative call destination.SELECTED DRAWING: Figure 10 【課題】携帯端末をインターホン親機の代わりに使用して遠隔で開錠を行うことが可能なインターホンシステムにおいて、鍵を開けられない状況の発生を低減する。【解決手段】代替呼出先として複数の登録者の利用する複数の通信端末（インターホン１０及び携帯通信端末３０）を予め登録しておき、インターホン１０は、呼出ボタンの押下に応じてカメラ処理を行って来訪者の動画像及び来訪者の顔特徴点を取得し、顔特徴点を含む通知データＮＦを認証サーバ２０に送信する。認証サーバ２０は、通知データＮＦに含まれる顔特徴点に基づき顔認証処理を行い、認証結果を含む呼出通知ＣＲを代替呼出先の複数の通信端末に送信し、この呼出通知に対して応答要求Ｒｅｑを送信してきた通信端末に対して来訪者の動画像情報を送信する。インターホン１０は、代替呼出先の通信端末のうち１つからでも開錠許可データＵＬｋｐを受信した場合に玄関ドアを開錠する。【選択図】図１０
